Singapore's Changi Airport station observations under southwest monsoon conditions recorded a daily maximum of 33°C on August 28, aligning precisely with the 100% market-implied outcome for that threshold. This matches official forecasts from Singapore's Meteorological Service projecting 33–34°C maxima for the latter half of August, driven by typical seasonal patterns where average daily highs reach 31.4°C and recent days consistently hit or approached 33°C. Strong model consensus and real-time station data from NOAA sources left little room for deviation, though late revisions to hourly readings or secondary sources like Weather Underground could theoretically shift the final verified peak within the day's measurement window.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=wsss
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
